"Images and open source code for the Touch Developer Preview of Ubuntu will be published on Thursday 21st February, supporting the Galaxy Nexus and Nexus 4 smartphones. They are intended for enthusiasts and developers, to familiarise themselves with Ubuntu's smartphone experience and develop applications on spare handsets. Tools that manage the flashing of the phone will be available on the same day in the Ubuntu archives, making it easy to keep a device up to date with the latest version of the Touch Developer Preview." Cool. Too bad it's only for Nexus phones, and not for more popular ones.
